ASPECTOS REPRODUCTIVOS DEL CLADÓCERO Moinodaphnia sp.EN CONDICIONES DE LABORATORIO

For their trofic rol in the aquatic ecosystems, Cladocera have been researched as live food in aquaculture for its small size, fast development, early reproduction, high rate of multiplication, nutritional value and easy care and cultivation. The root of cladocera was obtained by isolating organisms from the Lorica Swamp and placing them under controlled conditions in the University de Cordoba of Lorica's Live Food Laboratory. The purpose of the esearch was to define the most important reproduction aspects of this organism as it is a species with a very high cultivating potential. The research took four periods of 12 days each. One hundred eight organisms were placed in multicell chambers and fed with the Chlorella and Ankistrodesmus microalgas in a 30X104 cel.ml-1. Results of the researched showed an average daily fertility rate of 3.44 Newborn/Female ± 0.097, an early stage fertility of 4.16 Newborn/Female ± 1.37, a generation time of 4.5 days ± 0.76, and a reproductive frequency of 30 hour. The results established that that organism has a high potential as a feeding organism due to its high fertility, short generation time and adequate reproductive frequency.
